Microsoft might be joining the 7 to 8-inch tablet bandwagon with a Surface mini. At the Goldman Sachs Technology and Internet Conference on Wednesday, Microsoft Chief Financial Officer Peter Klein hinted that his company is ready to embrace a different size form factor for the Surface.

“We can have the same core code base driving form factors from four inches all the way up to 27-inch ones and everything in between,” Klein said. “So I think we are well set up to respond to demand as we see it. We can deliver a versatile set of experiences across form factors, whether they’re four-inch, five-inch, seven-inch, 10-inch or 13-inch.”

Klein said that Microsoft always planned “flexibility and scalability” into its Surface production line.

Microsoft has had a tough time selling the 10-inch Surface. It’s been noted many times that Surface sales have been lagging behind that of Android devices because of the higher price point and smaller app library.

It isn’t yet clear what form factor Microsoft will push for its new Surface tablet. The usual supply chain watchers, such as Digitimes, aren’t reporting orders for a certain size of display panels — which would be indicative of the size of tablet Microsoft is going for.

There is some speculation that Microsoft may ditch the Windows RT operating system in favor of Windows Phone 8 if it goes chooses to produce a smaller Surface. Both Windows RT and Windows Phone 8 share the same kernel.

Of course Microsoft could try and create a larger tablet for its next-generation Surface. It was reported that Microsoft may be working on a 14.6-inch “Surface Book” powered by a next-generation 22nm Haswell chip from Intel.
